HINGE FOR SOFA-BEDS, 800.

SPECIFICATION forming part of Letters Patent No. 762,094, dated June '7, 1904.

Application filed March 28, 1903'.

To all whom it may concern.-

Be it known that I, FRANK J. SENG, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Hinge for Sofa- Beds, &c., of which the following is a specification.

This invention relates to sofa-beds of the class wherein the back is adapted to be swung downward and into a horizontal plane with the seat, which latter is stationary, whereby, as will be obvious, it is first necessary to withdraw said sofa bed a sufficient distance from the wall.

The objects in view are to provide a novel and useful form of hinge so constructed as to permit of the back being raised vertically and bodily a sufficient distance to enable its upholstering to clear that of the seat, so that the back may be folded upon the seat when the latter is upholstered and also when lowered into bed form to be moved forward against the rear edge of the upholstering of the seat, whereby the upholstering of the twothe seat and back-will form a comfortable and practically unbroken bed or mattress surface.

A further object is to provide means for unlocking, opening, and locking the back-closing gates designed to protect the back when the sofa is used as such and to carry out the general design of a bed when opened for that purpose.

Referring to the drawings, Figure 1 is a- View of a sofa-bed, one side removed and the back lowered to form a bed. Fig. 2 is an enlarged view in detail of the hinge, the parts composing the same being shown in full-lines in the position they occupy when the back is folded over upon the seat and in dotted lines as when in sofa form. Fig. 3 is a similar view, the parts composing the hinge being shown in the same position as in Fig. 1.

Similar numerals of reference indicate'similar parts in all the figures of the drawings.

In the present instance 1 designates the boxsection forming the base of the sofa-bed and which is usually found present in this class of sofa-beds. 2 designates the sides, 3 the seatframe supported by the box-section or base, and 4 the movable back-frame. Secured to the back and seat frames are removable cush- Serial No. 150,044. (No model.)

tal plane with the seat combine to produce a bed.

The improved hinge for movably connecting the seat and back frames together, it will be understood, is duplicated at each end of the sofa. This hinge comprises opposite substantially duplicate leaves 6 and 7, the former being attached'to the outer side of the side rail of the seat-frame at its rear end and the latter being similarly located on the side rail of the back-frame. For the purpose of facilitating their application each leaf 6 and 7 may be provided with suitable screw receiving holes and with angularly-disposed lugs 8 at two or more of their corners, against which the framing of the seat and back sections may abut. I

At their upper meeting corners each leaf is formed with a diagonally-extended portion or pintle 9, immediately in rear of which a lateral stop-lug 10 may be formed. Pintles 11 are mounted in each ear 9, that of the leaf 6 passing through the upper end of a standard or other support 12 and also through the lower end of a loose connecting-link 13 and the pintle 11 of the companion leaf 7 passing loosely through and adapted to freely ride in a longitudinal slot 14, formed in the opposite half of said link. The hinge thus constructed is preferably cheaply and conveniently formed of sheet metal of suitable gage.

Taking the parts in the position shown in Fig. 2 it will be apparent that by reason of the presence of the slotted connecting-link 13 the leaf 7, and-consequently the back-section, is extensibly pivoted on the leaf 6 and capable of both pivotal and slidable movements, and therefore of a vertical elevation of the back section or frame until its upholstering or cushion clears the cushion of the seat-frame, so that the back may be folded over upon the seat or elevated, so as to form and have the appearance of an ordinary sofa.

It will be perfectly obvious that the backsection can be readily lowered to a horizontal position, the upholstering serving to draw the said back-frame forward a slight distance when released until the adjacent edges of the two frames abut. In this manner the two bodies of upholstering are caused to combine and produce practically an unbroken bed or mattress surface. When it is desired to elevate the back section or frame, it is simply necessary to force the same rearward against the tendency of the body of upholstering the limit of the slot 1 1 and elevate said section. The independent movements of the back section or frame described is the result of employing the slotted intermediate connectinglink 13. When the back is elevated, as shown by dotted lines in Fig. 2, the pintle 11 of the leaf 7 is at the inner end of the slot 14 of-the link 13, the latter occupying a horizontal position, and when lowered, as shown in Fig. 3, the said pintle occupies the same position, and likewise the link.

It is usual to provide the frames of such sofa-beds with some style of support for the rear end of the back section or frame when lowered. One convenient way of accomplishing this is to hinge to the opposite edges of the sides 2, by means of ordinary hinges 15, a pair of gates 16, which may be closed when the back is elevated or opened when the same is lowered. Cleats 17 may be secured to the inner surfaces of the gates and these utilized as supports for the back-frame when the latter is lowered. These gates may be secured in their closed position by anysuitable means for example, pairs of latches 18, adapted to engage rearwardly-projeeting catches 19, the latter being fixed to the back of the sofa and the former pivoted in slots 20, so that their rear ends or tails extend backward beyond the gates a sufficient distance to accommodate the toe of the boot, by means of which said latches may be depressed at their rear ends, and hence disconnected at their front ends from the catches 19. It will further be seen that when the back is lowered the stop-lugs 1O engage over the link 13 at each side of the supportingstandard, and hence said link affords a most rigid support for the front end of the back section or frame.

The standard 12 may be omitted and the pintle 11 of the leaf 6 secured direct to the side 2; but if employed (and it is greatly preferred) its lower end is best stepped into a socket-keeper 22, the lower end of which is closed, as indicated by dotted lines, Fig. 3.

Having described my invention, what I claim is l. The combination in asofa-bed, of seat and back sections, a pair of hinge-leaves secured to each of the same, intermediate pintle-supports therefor, and links pivotally connected to those leaves of the seat-section, and to the pintle-support, said links each being provided with a straight longitudinal slot by means of which it is connected to those leaves of the back-section, whereby the latter leaves are adapted for both pivotal and longitudinal movement.

2. The combination, in a sofa-bed, of movable seat and back sections, a pair of hingeleaves mounted upon each of the same, one leaf of each pair having a pintle, intermediate supports, and links connecting the pairs of leaves of the two sections, each of said links being pivotally connected to one of said intermediate supports, pivotally connected at one end to one of said leaves, and provided near its opposite end with a straight longitudinal slot by which it is engaged loosely and slidably with said pintle of the remaining leaf.

3. The combination,inasofa-bed,ofseatand back sections, opposite pairs of hinge-leaves each provided with a pintle, and an intermediate connecting bar or link having one end pivotally connected to one of the pintles and near its opposite end provided with a straight longitudinal slot by means of which it loosely engages the remaining pintle.

1. The combination, in a sofa-bed, of a seat and a back section, opposite pairs of hingeleaves each provided with a pintle, and an intermediate'connecting-bar for each pair of leaves, said bar being pivotally mounted on the pintle of that leaf attached to the seat-section provided with a straight longitudinal slot and loosely mounted on the pintle of that leaf attached to the back-section.

5. The combination, in a sofa-bed, of a seat and a back section, a pair of hinge-leaves connected to the ends of said sections, each of said leaves being formed with an extended pintle-ear, a pintle mounted in each ear, supports connected to the pintles ofthose leaves attached to the seat-section, and a connecting bar also mounted pivotally on each of said pintles, and near its opposite end slotted and loosely connected to the pintle of that leaf connected to the back-section.

6. The combination, in asofa-bed, of a seat and back sections, a pair of hinge-leaves connected to the ends of said sections, each of said leaves being formed with an extended pintleear, a pintle mounted in each ear, supports connected to the pintles of those leavesattached to the seat-section, and a connecting bar also mounted pivotally on each of said pintles, and near its opposite end slotted and loosely connected to the pintle of that leaf connected to the back-section, each of said leaves being provided with stop-lugs at the FRANK J. SENG.
